Could you show the code ?

There must be a place where you decode JSON (deserialize).
Maybe your JSON data is incorrect ?
That can cause such type of error (even though not the same error as yours) : https://stackoverflow.com/questions/46284163/alamofire-responseserializationfailedalamofire-aferror-responseserializationfai

Did it work before Xcode 12.5 ?
Are you sure to have the most recent Alamofire pod version ?

I cannot use latest Alamofire because after tag 4.8.2, they removed WWAN connectivity apis. That is critical for my app. The issue is not just with Alamofire. It is with SwiftSocket and CocoaMQTT libraries too. And the issue only came up after I upgraded my xcode.

So that could well be a compatibility issue between the pod and Xcode 12.5.

You'd better ask Alamofire editor.

Where did you read this ?
Unfortunately, that means that you will have to adapt your app anytime soon.
